NGTS clusters survey - VII. An Enigmatic Short-Period Circumsecondary Disk Candidate in Orion

Niamh Mallaghan, Ernst J. W. de Mooij, Christopher A. Watson +31

Young stellar systems provide key insights into the processes governing star/planet formation, often exhibiting complex and evolving photometric variability. In this paper, we pres…

High-Precision Photometry with a scientific CMOS Camera: II On-Sky Testing of the Marana camera at the NGTS facility

Ioannis Apergis, Daniel Bayliss, Paul Chote +24

Modern scientific CMOS cameras offer very fast readout speeds and low read noise. In this study, we evaluate the performance of the Andor Marana CMOS camera through on-sky testing…

A 43 day transiting Neptune and two 25 day Saturns from TESS, NGTS and ASTEP

Alicia Kendall, Solène Ulmer-Moll, Samuel Gill +53

Beyond orbital periods of 10 days, there is a dearth of known transiting gas giants. On longer orbits, planets are less affected by their host star, and become ideal probes of plan…

TOI-333b: A Neptune Desert planet around a F7V star

Douglas R. Alves, James S. Jenkins, José I. Vinés +29

Observations have shown that planets similar to Neptune are rarely found orbiting Sun-like stars with periods up to ~4 days, defining the so-called Neptune desert region. Therefore…

TOI-2490b- The most eccentric brown dwarf transiting in the brown dwarf desert

Beth A. Henderson, Sarah L. Casewell, Andrés Jordán +40

We report the discovery of the most eccentric transiting brown dwarf in the brown dwarf desert, TOI02490b. The brown dwarf desert is the lack of brown dwarfs around main sequence s…

Photo-dynamical characterisation of the TOI-178 resonant chain

A. Leleu, J. -B. Delisle, L. Delrez +104

The TOI-178 system consists of a nearby late K-dwarf transited by six planets in the super-Earth to mini-Neptune regime, with radii ranging from 1.2 to 2.9 earth radius and orbital…

TOI-2447 b / NGTS-29 b: a 69-day Saturn around a Solar analogue

Samuel Gill, Daniel Bayliss, Solène Ulmer-Moll +63

Discovering transiting exoplanets with relatively long orbital periods (10 days) is crucial to facilitate the study of cool exoplanet atmospheres () and to u…

Planet Hunters NGTS: New Planet Candidates from a Citizen Science Search of the Next Generation Transit Survey Public Data

Sean M. O'Brien, Megan E. Schwamb, Samuel Gill +35

We present the results from the first two years of the Planet Hunters NGTS citizen science project, which searches for transiting planet candidates in data from the Next Generation…
